You're not reading the show quite right. It's not supposed to be heartwarming stories about people showing compassion, it's understated character-driven humor about people who act badly, while still being cute. Cute, and appealing to the pedos, there's no denying that.
And if you don't care what some guy on the internet says, how about a dictionary?
